[dhcp_relay]: Check whether device requires DHCP relay upon docker start #371

jleveque · 2017-03-03T18:54:06Z

If not, log a message and exit docker. Other conditions can be added in the future as needed.

With OneImage, all dockers must be deployed, but DHCP relay may not be needed. It's cleaner to have docker exit than to continue running and serving no purpose. Log message is helpful to understand why.

dockers/docker-dhcp-relay/config.sh

+DEVICE_ROLE=`sonic-cfggen -m /etc/sonic/minigraph.xml -v "minigraph_devices['$MINIGRAPH_HOSTNAME']['type']"`
+
+if [ $DEVICE_ROLE != "ToRRouter" ]; then
+    echo "Device does not require DHCP relay. docker-dhcp-relay exiting..."


if the script exits here, will the docker exits?

I think if you return a nonzero value, it will.

Taoyu is correct. I have tested the behavior, and exiting with a nonzero value will cause the docker container to exit, whereas exiting with a return value of 0 will cause the container to keep running.

dockers/docker-dhcp-relay/config.sh

-sonic-cfggen -m /etc/sonic/minigraph.xml -y /etc/sonic/dhcp_relay.yml -t /usr/share/sonic/templates/isc-dhcp-relay.j2 > /etc/default/isc-dhcp-relay
+MINIGRAPH_HOSTNAME=`sonic-cfggen -m /etc/sonic/minigraph.xml -v "minigraph_hostname"`
+DEVICE_ROLE=`sonic-cfggen -m /etc/sonic/minigraph.xml -v "minigraph_devices['$MINIGRAPH_HOSTNAME']['type']"`
+


you can directly use -v "minigraph_devices[minigraph_hostname]['type']", don't need to call it twice.

Good to know. Simplified in 0fdd3c8. Thanks!

should we do this in dhcprelay service unit file? if we detect it is not tor, we do not even start the container.

jleveque · 2017-03-09T00:26:34Z

It would be cleaner to have this logic outside the container, but systemd provides a limited set of conditionals to work with in the unit files, none of which I'm aware of allow us to directly check the device type from the minigraph. Do you have an idea in mind?

taoyl-ms · 2017-03-17T22:45:09Z

How about doing it in /usr/bin/dhcp_relay.sh instead of in the service definition file? You can check minigraph there and if the switch is not ToR you just do nothing and tell systemd you succeeded to start the service.

jleveque · 2017-03-17T23:43:06Z

Thanks for the idea, but after speaking with Guohan and Shuotian, we decided the service shouldn't even be started if not needed. This also applies to teamd, and may apply to other services in the future. I will soon submit another solution that disables the services on first boot.

taoyl-ms · 2017-03-18T02:25:45Z

If you are going to disable the service on first boot, please make sure your disabling happens after update_graph service so we don't mistakenly disable it based on a default graph.

jleveque · 2017-03-18T21:14:00Z

Thanks for the heads-up! :)
